Seahawks cut Johnson to make room for Jackson

The Seahawks officially announced today that they had added Tarvaris Jackson to the roster.

To make room on the 90-man roster, Seattle cut quarterback Jerrod Johnson, a first-year quarterback from Texas A&M who had been working as the No. 3 quarterback since signing in April.

The roster shuffle leaves Seattle with three quarterbacks on its roster in starter Russell Wilson, Jackson, and Brady Quinn.

Seahawks coach Pete Carroll said Thursday that Jackson and Quinn will battle it out for the backup spot. Conventional wisdom, though, is that the No. 2 job will be Jackson’s to lose given that he started 14 games for the Seahawks in 2011 and has a familiarity with the playbook and most of the personnel.

That may leave the more intriguing question of whether the Seahawks will keep three quarterbacks, or try to make due with two as they did most of last season.
